This reminds me of a comic, which obviously should be taken playfully with a pinch of salt:

• Two Italian men are joined by a visitor trying to ask a question in Italian. “Ah, they’re trying to speak Italian!” and so they turn to the visitor and welcome them in Italian.
• Two German men are joined by a visitor trying to ask a question in German. “Ah, they’re trying to speak German!” and so they turn to the visitor and welcome them in English.
• Two Parisian men are joined by a visitor trying to ask a question in French. “Ah, they’re trying to speak French!” and so they turn away and ignore them.
